Two British auction houses are joining forces to take on the colossal task of auctioning off the estate of the late pulibsher Felix Dennis. The auction will gather together Dennis’s possessions from his 12 homes around the world, to be sold in a 20,000 square-foot marquee near Stratford-upon-Avon from September 29 to October 1.

Willem Peppler’s diverse art collection will be auctioned off at Christie’s in the end of October. Including many rare gems and pieces that have never been near a gavel before, this auction is set to be just as exciting as the artwork.
